(Config).SessionTicketKey

Description

SessionTicketKey is used by TLS servers to provide session
resumption. See RFC 5077. If zero, it will be filled with
random data before the first server handshake.

If multiple servers are terminating connections for the same host
they should all have the same SessionTicketKey. If the
SessionTicketKey leaks, previously recorded and future TLS
connections using that key are compromised.
